Doug I use DM-780 and discovered the same thing you are experiencing once in a while. I finally figured out what I was doing wrong.  I narrowed down my K3 filter to 250 hz and saw on the display that I was centered on 1500 hz in Data A mode but when I switched to AFSK for RTTY it was centered on 1000 hz. If If I click on a waterfall very far from the 1000 hz I will not hear or tx the tones. Try finding your center BW tone/freq on the waterfall and tune the station to that and see if your monitor and tx output works.

no RF and do not  
hear anything on Monitor playback.

Everything works OK in Data A both RTTY and PSK.
